SPECIFICATION forming part of Letters Patent No.4559,417, dated May 5,1896. lpplication lerl January 1'7, 1895, Serial No. 535,266. (Nomodel.)

T0 all whom t may concern.'

Be it known that I, WILLIAM BARTON SPEN- CER, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Vaginal Syringe, of which thefollowing is a specification.

This invention relates to vaginal syringes; and it has for its object toeffect certain improvements in syringes of this character whereby thesame shall be rendered safer to use and more efficient in operation.

To this end the main and primary object of the invention is to provide avaginal syringe in which the injecting-nozzle thereof shall besufficiently yielding and adjustable so as to be adapted for use indifferent cases without the slightest degree of pain or injury to thepatient, and the invention therefore contemplates a construction ofsyringe that may be easily and readily assembled, taken apart, cleaned,disinfected, and the nozzle of which can be adjusted almost'universally,so as to meet all requirements, and 4thereby obviate the disadvantagesof vaginal syringes having stiff unyielding nozzles, which are ofteninjurious in inexperienced hands. In the attainment of the objects notedthe syringe is designed as an improvement upon the class of syringesshown in my former patent, numbered 474,506.

Vith these and other obj ects in view, which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination, and arrangement of parts hereinaftermore fully described, illustrated, and claimed.

In the drawings, Figure l is a perspective View, partly in section7 of avaginal syringe constructed in accordance with this invention, showingin dotted lines some of the possible adjusted positions of the flexiblenozzle. Fig. 2 is a `central vertical sectional view thereof. Fig. 3 isa view similar to Fig. 2, showing a modied construction of nozzle.

Figs. 4, 5, and 6 are detail elevations of different forms of themodified construction of nozzle shown in Fig. 3. Fig. 7 is a detail incushion 2, that provides an easy and soft con- `tact with the body, andat its :lower tapered end the receiver is provided with `an extended.discharge-pipe 3, that is exteriorily reduced `to form anattaching-neck 4, to detaehably receive one end of the flexibledischarge-tube 5, which provides for conducting the liquid dischargefrom the backfiow-receiver to any suitable receptacle.

The receiver l is provided at `an interme diate point between its upperand lower ends with a side tube-opening 6, in which is adapted to betted the flexible supply-tube 7 that leads from an ordinary bulb,fountain, or other injection syringe, and said tube 7 may either be acontinuous tube, as a part of the bulb or other syringe, or maybe aseparate section of tubing, as illustrated in one of the figures of thedrawings, and provided at one end with an attaching-nipple 7 f, on whichis adaptedA to be fitted the circulating-pipe of the bulb, fountain, orsimilar syringe. The fieXible supply-tube 7 is slightly greater indiameter than the side tube-opening 6, in which it is fitted, so thatthe tube will be pinched sufficiently tight in said opening to hold itfirm in its adjusted position, and the 'said supply-tube extends intoand above the receiver l to form an adjustable flexible nozzle portion9, that is adapted to be inserted into the vaginal canal to give thedesired injection or douche. The nozzle "portion 9 of the tube 7 isadapted to have fitted on its upper end a bulbous perforate nozzle-tiplO, which may be made of any suitable material, and is adapted todistribute or spray the liquid within the vaginal canal to reach theaffected parts, and the said nozzle-tip may be made in various lengthsor sizes to provide for lengthening or shortening the nozzle portion ofthe syringe and with any desired number or character of perforations tosuit a particular case.

IOO

By reason of forming the nozzle of a syr.

inge of a portion of the iiexible supply-tube it will be obvious thatthe nozzle can be moved, bent, or adjusted in various positions, asshown in Fig. l of the drawings; but this form of the nozzle issusceptible to slight modifications, as illustrated in Figs. 3, 4, 5,and 6. In Fig. 3 of the drawings the upper end of the supply-tube 7,that is projected from within the receiver l, is provided with anattaching-nipple 1l, onto which is adapted to be tted the lower end of aflexible nozzletube 9, consisting of a short length or section of softor iieXible tubing and corresponding in use and adjustment to thenozzle-tube portion 9, previously referred to. The :nozzletube 9 may bemade in various lengths and sizes, according to the character of thework required of the syringe, and said tube may be imperforatethroughout its length, as shown in Fig. 3, perforated throughout itslength, as shown in Fig. 4, or perforated throughout its length at oneside only, as illustrated in Fig. 5, to provide, by turning thenozzle-tube, for directing the douchingjets to any special ulcer orspot. In the several modified forms of nozzles the same are all providedwith the separate detachable nozzle-tips 10, previously referred to, andin Fig. 6 is illustrated a modified construction of nozzle-tip 10, thatis imperforate and open at both ends to provide for attachment to thenozzle-tube and for directing a steady unbroken stream of liquid intothe vaginal canal.

In all forms of the syringe the portion of the flexible supply-tube 7within the backflowreceiver is maintained centrally positioned thereinby means of the rigid curved nozzle-supporting arm l2. The curvednozzlesupporting arm 12 is made of hard rubber or other suitable stiffmaterial and is semicircular in cross-section, so as to embrace one sideof the tube 7, and at its opposite upper and lower end the said curvedsemicircular arm l2 is provided with the clamp rings or collars 13, theupper of which is slightly smaller in diameter than the tube 7 ,toprovide for tightly gripping the same. Vhen the parts of t-he syringeare properly adjusted, the lower end of the arm l2 rests against theinner side of the receiver l, directly over the side opening G therein7and owing to the tight fit of the' tube 7 in said opening 6 it will beobvious the said arm will be retained in its upright position forproperly supporting the nozzle and will withstand any tendency of thetube 7 to collapse downward within the receiver, and while thedisposition of the arm l2, resting at its lower ond against one side ofthe receiver, will ordinarily be sufficient to hold said arm properly inposition ascrew or other suitable fastener 14 maybe engaged with thelower end of the arm to secure the same to the receiver, as illustratedin Fig. 3 of the drawings.

The specific manner of supporting the fieXible nozzle-tube within thereceiver provides also for the length adjustment of said nozzletubeirrespective of the length of the tip lO or in the modification of thetube-sections 9, and this adjustment is secured by drawing thenozzle-tube 7 in either direction through the supporting-arm 12 and theopening 6, it being again noted that the pinching or gripping of thetube 7 at the points 6 and 13 provides for holding the same tight in itsadj usted position.

The use of the herein-described syringe will be well understood by thoseskilled in the art; but attent-ion may be directed to the fact that byplacing the supply and discharge tubes 7 and 5 in the same receptacle acontin nous circulation through the syringe may be provided for, whichis very desirable in certain cases, and by detaching the tube 5 andplugging the pipe 3, as at 15, (shown in dotted lines in Fig. 2,) theliquid, such as hot water, may be backed up to and held at the very seatof disease. Other uses of the syringe will suggest themselves.

Changes in the form, proportion, and the minor details of constructionmaybe resorted to without departing from the principle or sacriicing anyof the advantages of this invention.

I-Iaving thus described the invention, what is claimed, and desired tobe secured by Letters Patent, is*

In a vaginal syringe, the combination of a backiiow-receiver having aside opening, a flexible supply-tube adj ustably fitted in said openingand having an extended iiexible nozzle portion, and a curvedsemicircular rigid nozzle-supporting arm arranged within and sustainedat its lower end against the inner side of said receiver, saidnozzle-supporting arm being provided at its upper end with a clamp ringor collar of a less diameter than and tightly embracing saidsupply-tube, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

WILLIAM BARTON SPENCER.
